Milk never runs out, lights go on by themselves when it gets dark outside. The car is warmed up and ready to go in winter, the house is always pleasantly cool in summer. What do you need to do to make this all happen? Nothing. In future – in fact, it’s already starting today – routine things are happening completely automatically because we are living with the Internet of Things (IoT) completely naturally. Equipment and machines are networked online and ‘thinking’ along with us. Like the refrigerator that orders food when it runs out. It applies to all areas of our life where annoying routine tasks are eliminated (such as thinking about milk on the way home), but the trade-off is dealing with more data, data analysis and date security. Nevertheless: The opportunities seem too good to leave unexploited. The Internet of Things could be particularly profitable for stationary retail, where the McKinsey Global Institute has predicted an annual potential of 410 billion to 1.2 trillion US dollars for 2025. To compare: The auto industry calculates making between 210 to 740 billion dollars. A lot of money.
